ABSTRACT

An environmental humidification and cooling system including an ultrasonic spray nozzle. Humidification is effected by spraying atomized water by the ultrasonic nozzle into the suction chamber of a fan. The cooling includes the ultrasonic spray nozzle spraying the atomized water into an entering air stream to effect evaporative cooling. Simultaneous evaporative cooling and humidification for an enclosed environment is effected by the spraying of moisture into a return air stream by the ultrasonic spray nozzle.
